We've resolved the exception on our side. Still, at this point, the functionality for focusing the next element does not work properly. This is caused by an issue on Xamarin.Forms side. You can directly track it on Github here https://github.com/xamarin/Xamarin.Forms/issues/7870.

Hi Markus,

We're working on resolving the exception, most probably a fix will be available in some of the upcoming releases.

As a temporary workaround, until Xamarin.Forms team resolves the issue at their side, you could replace the next button with "Done" button through a custom renderer on Android. You would need to access the inner EditText control and set its ImeOptions property. Here is a quick example:

Copy Code

public class CustomDataFormRenderer : DataFormRenderer

{

public CustomDataFormRenderer(Context context) : base(context)

{

}

protected override void UpdateEditor(EntityPropertyEditor editor, Telerik.XamarinForms.Input.DataForm.IEntityProperty property)

{

base.UpdateEditor(editor, property);

if (editor is DataFormTextEditor || editor is DataFormDecimalEditor || editor is DataFormIntegerEditor)

{

var editText = editor.EditorView.JavaCast<AppCompatEditText>();

editText.ImeOptions = global::Android.Views.InputMethods.ImeAction.Done;

}

I applied the work-around for a few of the editors of the DataForm, you could add the other text editors you're using in your app.

Our investigation showed that it is caused by the TabIndex feature of Xamarin Forms that has been introduced with version 3.3. We have logged an issue on Xamarin.Forms repo : https://github.com/xamarin/Xamarin.Forms/issues/4561
